Function Documentation

void explain_connect_or_die	(	int	fildes,
		const struct sockaddr *	serv_addr,
		int	serv_addr_size
	)

The explain_connect_or_die function is used to call the connect(2) system call. On failure an explanation will be printed to stderr, obtained from the explain_connect(3) function, and then the process terminates by calling exit(EXIT_FAILURE).

This function is intended to be used in a fashion similar to the following example:

 explain_connect_or_die(fildes, serv_addr, serv_addr_size);

Parameters:

fildes	The fildes, exactly as to be passed to the connect(2) system call.
serv_addr	The serv_addr, exactly as to be passed to the connect(2) system call.
serv_addr_size	The serv_addr_size, exactly as to be passed to the connect(2) system call.

Returns:

This function only returns on success. On failure, prints an explanation and exits, it does not return.
